EIA JESD 8-29:2016

This standard defines power supply voltage range, dc interface, switching parameter and overshoot/undershoot for high speed low voltage swing terminated NMOS driver family digital circuits with 0.6V supply. The specifications in this standard represent a minimum set of interface specifications for low voltage terminated circuits. The purpose of this standard is to provide a standard of specification for uniformity, multiplicity of sources, elimination of confusion, and ease of device specification and design by users. Class 1 describes low VOH (Nominal VOH = VDDQ*0.5) level terminated electrical characteristics. Class 2 describes high VOH (Nominal VOH = VDDQ*0.6) level terminated electrical characteristics.
